Question

draw the graph of the equation 2x-y=1, x+2y=13 find the solution of equation from the graph and shade the triangular region formed by the lines y-axis.​

Answer 1

Explanation:

2 x - y = 1     and     x + 2 y = 13

The two lines intersect at x = 3  y = 5

see diagram for the solution and shaded area (Gray) ABC is formed the lines and the Y Axis.

The shaded area (BLUE) is formed by the lines and X-Axis

Hope it helps you

make it brainliest please ❤️❤️

Answer 2

Explanation:

Let the equations are,

2x-y=1 ----1

x+2y=13 ----2

1--- -y=1-2x

y=-1+2x -----3

3--- x=0

y=-1+2*0

y=-1

x=1

y=-1+2*1

y=1

x=2

y=-1+2*2

y=-3

x 0 1 2

y -1 1 -3

2--- x=13-2y----4

4--- y=0

x=13-2*0

x=13

y=1

x=13-2*1

x=11

y=2

x=13-2*2

x=9

x 13 11 9

y 0 1 2

Hope you can do the graph for these equations with the given solutions.

Sorry for this I can't do graph here so that only.
